Low rates of streptococcal pharyngitis and high rates of pyoderma in Australian aboriginal communities where acute rheumatic fever is hyperendemic.

BACKGROUND Acute rheumatic fever is a major cause of heart disease in Aboriginal Australians. The epidemiology differs from that observed in regions with temperate climates; streptococcal pharyngitis is reportedly rare, and pyoderma is highly prevalent. A link between pyoderma and acute rheumatic fever has been proposed but is yet to be proven. Group C beta-hemolytic streptococci and group G be...

An epidemiological study of rheumatic fever and rheumatic heart disease in Lagos.

In Lagos 12 755 schoolchildren aged between six and 12 years were screened for evidence of rheumatic heart disease and showed a prevalence rate of 0.03%. Group C (27.7%) and group G (47.3%) predominated in the throat and in cases of pharyngitis, while group A predominated on the skin. Two hundred and sixty-six cases of pharyngitis were recorded, 70 (26.4%) were positive for beta-haemolytic stre...

Studies upon Minute Hemolytic Streptococci

1. Minute beta hemolytic streptococci were found to occur from one-third to one-half as frequently in normal individuals as do ordinary beta hemolytic streptococci. 2. They were rarely isolated from the rhinopharynges of individuals suffering from chronic disease. 3. In acute respiratory tract infection other than that due to the ordinary beta hemolytic streptococcus the incidence of minute str...
